Neutro CO₂ - Liquid Carbon for planted aquariumsNeutro CO is a liquid source of carbon for the planted aquarium. For those of you not familiar with it, carbon is essential for all healthy plant growth and can be provided via gas, or liquid. The liquid form is less potent than gas but still very effective. It won't make your plants pearl (this is when you see O2 bubbles coming from the plant) but it will help them grow. Plants that have access to liquid carbon will do far better than those without.

This is one of the healthier sunscreens I’ve found so far. You’re not likely going to find a mineral sunscreen that doesn’t leave some white cast. However, this one rubs in pretty good with minimal cast. You can dab on and rub in fairly easily… as long as you don’t use too much the white cast should be minimal. I am not sure how well this would work on darker skin tones. My arms are a medium skin tone… my legs are more of a light-medium tone. I prefer mineral sunscreens, and this is the best one I found so far and compatible to Supergoop mineral play. If you liked that one, you would likely enjoy this Coola one too.

Would not recommend

Style: SPF 50

I literally never write reviews but felt compelled to write one for this sunscreen because I was very caught off guard by all the positive reviews. This sunscreen leaves the most insane white sheen that never soaks in and gets on EVERYTHING. I put this on and drove to the beach and had sunscreen on my car seat, the steering wheel, the center console, the door, EVERYWHERE! It took forever to clean up and was such a hassle and that was after having let the sunscreen soak into my skin for an hour. Also the sunscreen is really thick and difficult to spread and makes you look ghostly white. Plus, the sunscreen has a really odd odor that reminded me of play dough? That might not be a negative thing for everyone but I found it unpleasant. There are definitely better mineral sunscreens out there. For the price I expected a much better product.

Sticky and white

Style: SPF 50

The sunscreen has a very sticky and thick texture. It will keep you from getting sunburnt, but it will also leave you with a white color.

Good sunscreen

Style: SPF 50

Super good coverage and it lasts a long time in the sun and even through water activities. The only negative is the white cast. Not as bad as others but just be aware it doesn’t fully rub in.

Great sunscreen & works for kids - even used in resorts!

Style: SPF 50

Terrific! I don’t feel it is as good as chemical ones but my favorite non-chemical one. Used on a long vacation and it did the job! Also didn’t cause pimples like other thick versions of this.
